Re: Ban because of sales?
You would have recieved an email about the ban, to the email linked with your account.
Unfortunatly the EA staff who work on AHQ cannot help you with account-related issues, such as bans.
If you feel you have been incorrectly banned, the only thing you can do is to dispute any action taken against your EA account by following the steps in this article:
